This is not a mental stop due to the short term nature of a day trade and the small size of the stop.
Bulls have gotten awfully quiet. Are the ones out there still waiting for the high 2400's? Do you ever go to sleep at night thinking one morning you will wake up and some blackswan will blow out your account in one day? Is it really worth trying to squeeze the last 1 or 2% out of this market?
There is no down to the equities market, it's only up up up. Are you crazy? Down market, pfft. Not possible.
They were saying this same thing a year or two ago. In actual fact, in any point in time one could raise this comment. No point thinking like this, otherwise one would forever be waiting for that 'perfect opportunity'. It's not about being reckless, neither being a scaredey pussy.
It's all about risk management. As long as one understands their blow up risk value and sizes accordingly, one can be comfortable in their position and know if shit hits the fan, they live to trade another day.
